Survey of Prison Inmates, United States, 2016

To fulfill part of its mission, the Bureau of Justice Statistics (BJS) conducted the Survey of Prison Inmates (SPI), a national, wide-ranging survey of prisoners age 18 or older who were incarcerated in state or federal correctional facilities within the United States. SPI provides national statistics on prisoner characteristics across a variety of domains, such as current offense and sentence, incident characteristics, firearm possession and sources, criminal history, demographic and socioeconomic characteristics, family background, drug and alcohol use and treatment, mental and physical health and treatment, and facility programs and rules violations. SPI can also be used to track changes in these characteristics over time, describe special populations of prisoners, and identify policy-relevant changes in the state and federal prison populations. Formerly the Survey of Inmates in State and Federal Correctional Facilities (SISFCF), this survey was renamed SPI with the 2016 iteration.

为履行其使命的一部分，司法统计局（Bureau of Justice Statistics，简称BJS）开展了囚犯调查（Survey of Prison Inmates，简称SPI），这是一项针对美国各州或联邦矫正设施内年龄在18岁或以上的囚犯进行的全国性、广泛的调查。SPI提供了关于囚犯特征的全国统计数据，涉及多个领域，如当前罪行和刑期、事件特征、枪支拥有和来源、犯罪历史、人口统计学和社会经济特征、家庭背景、药物和酒精使用及治疗、心理和身体健康及治疗，以及设施项目和规则违规情况。SPI还可以用于追踪这些特征随时间的变化，描述特殊囚犯群体，并识别州和联邦监狱人口中政策相关的变化。原名为州和联邦矫正设施囚犯调查（Survey of Inmates in State and Federal Correctional Facilities，简称SISFCF）的该调查在2016年版本中被更名为SPI。
